The prostate-specific antigen (PSA) test is a blood test used to screen males for prostate cancer. Prostate cancer is the second leading cause of death related to cancer among men in the United States. It is important that men approaching increasing age have their PSA levels checked. Obana and O’Lawrence (2015) stated that males over the age of 40 who have a family history of prostate cancer can benefit from electing to have their PSA levels checked. Those that do not have a family history of prostate cancer can also benefit from PSA testing, but it is not recommended as strictly until the population nears 50 years of age. The test is a simple blood test that involves a blood sample being drawn and sent to a laboratory for analysis. Once the results are determined, a healthcare provider can inform the patient of the results and discuss the indications. The test detects high levels of PSA in the blood, which should not be present in large amounts. High levels of PSA in the blood may indicate prostate cancer. Nordström, Adolfsson, Grönberg, and Eklund (2017) stated that PSA tests are an extremely useful first-line risk assessment for prostate cancer, but the test needs to be followed up with more conclusive testing for diagnosis if a man’s PSA levels are elevated. PSA testing is quick and inexpensive, making it an attractive option for initial prostate cancer screening. However, for diagnosis, more definitive diagnostic tests such as ultrasound, biopsy, or MRI fusion need to be performed (Nordström, Adolfsson, Grönberg,
